RAIL-FASTENING.

Specification of Letters Patent. Application filed 0ctober'21, 1912.

Patented Dec. 2, 1913. Serial No. 727,05

is of greatest importance. First of all, the

sleeper must, if possible, not be perforated and, further, the rail must receive an immovable arrangement. According to the present invention, the rail is, under this consideration, connected with the sleeper by electric welding. Thereby, a faultless-connection of the rail with the sleeper is obtained andan exact, proper and permanent mountin of the rail on the sleeper is secured; hanges of the ,width of the track or of the inclination of the rails in curves are impossible, while, further, the rail. is prei entedfro-m creeping and, finally, a most reliable transmission of pressure on the sleeper is secured. Of greatest importance is further the easy and quick way of fixing the rail on the sleeper, and the impossibility connection without comof loosening this plicated auxiliary means,

so that accidents, which hitherto happened owing to criminal disconnection of rail and sleeper, arenow practically impossible. I

The fixin of the rail on the sleeper by electric wel ing may be effected .either' directly or through the medium of a correspondinglywedge-shaped tie-plate. As the rail forms then with the latter and the sleeper a homogenous body, any loosleining is impossible. The disconnection is y possible in a mechanical or thermic way, the welded sections being in the former case sawed or bored asunder or,-while in the latter case they must again be brought on Welding heat in ordertobe separated.

The accompanying dra vingshows the improved arrangement. 7

Figure l is a cross section, and Fig. 2 a plan View, of the improved rail-fastening.

The sleeper ,a is, according to the invention, connected with the rail 6 through the medium of a correspondingly wedge-shaped tie-plate c in such a way that single points 0 which touch each welded. This may be effected by holding electrodes d of a stationary or movable power source on said points until the latter are brought on welding heat whereupon they may be at once'connected by a slight pressure only. The rail-fastening, as above described, can thus be eflected in a very easy and safe way and need no later attendance, while it insures the greatest securit and rigidity of the connection. The s eeper itself may further be provided with ribs, or,

with a single rib or projection, which serves as a strengthening for the same. The Welding may be effected on any size of surface, which can therefore be larger than the stronger section of the parts to be welded;

I claim: v A rail fastening consisting of a sleeper and an intermediary tie-plate, the latter being welded together and the tie-plate to the rail in an electric way. r In testimony whereof I have hereunto set other. are electrically my hand in the presence of two subscribing witnesses.
